4.2.17 Factory Reset
In some rare cases, if the sensor fails to operate properly, a factory reset might be needed, which can be
done in the App, or manually via the reset hole in the back of the Cypress sensor, or the reset button at
the top of the Sentinare 2 sensor.
1) Factory Reset via the App
If the sensor can be connected to the App via Bluetooth, the factory reset can be done via the App by
selecting the Factory Reset command in the advanced setting of the sensor page. This is convenient
when the sensor is installed at a high position that is not easy to access.
For the Cypress sensor, the reset process takes about 2 minutes, during which the sensor’s LED will
change to flashing green, flashing white, solid white (rebooting), and finally flashing white, signaling that
it is ready to be added to an account. Some firmware versions might need multiple reboots. Please do
NOT unplug its power until the sensor is fully reset after two minutes, and the LED becomes flashing
white light. After the factory reset, the sensor’s firmware will revert to the initial version, all user data
will be erased from the sensor, and the sensor will be removed from the current account. It can then be
added to any account, after which the firmware needed to be upgraded.
